2 Claims.

The present invention relates to a container for rolls of paper.

Large quantities of waxed paper are sold in small rolls for householdand other uses and a preferred form of marketing this sort of wax paperis in cardboard containers constructed so that the waxed paper may bewithdrawn from the container in such a manner that an edge of thecontainer may be used in severing the waxed paper from the roll. Varioustypes of containers have been constructed to fulfill these requirementsto a greater or less degree.

An object of the present invention is to construct a strong and simplecontainer for paper rolls wherein an edge of the container acts as asevering element for the paper contained therein.

In order to attain this object, there is provided, in accordance withone feature of the invention, a cardboard container cut to apredetermined shape and folded to form a rectangular container with' ahinged cover, a forward wall of the cover overlapping the forward edgeof the box, and the side walls of the cover each having a portionthereof folded inwardly and in contact with the forward edge of thecover to form a strong corner connection therewith.

These and other features of the invention will be more fully brought outin the following description and the accompanying drawing, wherein:

Figure 1 is a plan view of a cardboard blank cut to form a containerembodying the present invention, the dotted lines indicating the linesof fold.

Figure 2 is an enlarged transverse sectional view through the container,showing a roll of paper therein.

Figure 3 is a view in perspective of an enlarged view of the inner sideof a comer of the cover.

Figure 4 is a sectional view on the line 4-4 of Figure 3; and

Figure 5 is a view similar to Figure 3, showing the parts stapledtogether.

Referring to the drawing in detail, the blank A, shown in Figure 1, iscut by means of a suitable die, not shown, in a manner well known in theart of cardboard box making to the shape indicated. The portion 1thereof forms the bottom of the container. Portions 2 and 3 form theside walls and the portion. 4 forms the cover. Extensions 5, 6, 7, and 8on the ends of the side walls 2 and 3 fold inwardly as illustrated inFigure 2 and the extensions 9 and 10 on the ends of the bottom portionof the blank are folded upwardly and secured exteriorly of theextensions 1930. Serial No. 475,558

5 and 7 and 9 and 10, respectively. Extensions 11 and 12 on the ends ofthe cover portion 4 are folded downwardly to form the ends of the coverand the tabs 13 and 14 are bent inwardly at right angles to the endportions 11 and 12 of the cover. The extension 15 which forms the frontwall of the cover is then bent downwardly over the tabs 13 and 14 and incontact therewith, and a U-shaped metal band 16 is clamped over thelower edge of the front wall of the cover to enclose and grip the loweredges of the tabs 13 and 14, as shown in Figures 3 and 4, to securelybind these parts together and to form a reinforcement across the loweredge of the front cover wall 15. then be punched in as at 17 to deformthe metal of the member 16 inwardly and more firmly grip the front coverwall 15 and the tabs 13 and 14.

In the modified form shown in Figure 5, the tab 13 is secured to thefront cover wall 15 by means of a staple 18, or it may be adhesivelysecured to the cover member, as desired. The roll 19 of waxed paper isinserted in the container, as shown in Figure 2, and the end thereof isbrought upwardly over the forward wall of the box and downwardly as faras the lower edge of the cover member will extend when the cover memberis closed. The cover is then closed to hold the paper in position. Towithdraw the paper from the container the cover is raised sufiicientlyto permit the paper to be grasped and the desired quantity of paper iswithdrawn from the roll. The cover is then closed to the position shownin Figure 2, and by pulling the sheet angularly sideways and upwards thepaper may be severed along the lower edge of the front cover wall. Afterthe paper has once started to tear, the strain on the cover wall is veryslight, but at the initial point of tearing, namely, at the edge of thesheet of paper, which is near the cornerof the cover, a considerableamount of force may be required. For

this reason it is essential that the connection between the front andside walls of the cover should be strong to prevent tearing loose thefront wall of the cover from the side walls thereof.

It'has been customary, instead of cutting a slot as at 20 parallel tothe side walls of the blank from which the box is formed, to cut a slotalong the lines 21 so as to make the tabs co-extensive with the frontwall of the box cover. These tabs are then brought back along the innerface of the side walls 11 and are secured as by stitching or adhesive.When the front and side walls are connected at their cornerintersections in this manner, a straight shear is imposed on the fasten-The assembled structure may ing means, and in this way the full load ofthe tearing strain would be placed on the securing medium.

In the present instance, the tab 13 being coextensive with the sidewall, a continuous strip of cardboard extends around the corner so thatthe strain imposed by the tearing of the paper at its initial point oftear, namely, the corner of the cover, is borne directly by thiscontinuous strip of material which extends inwardly around the corner.When the tear has progressed past the tab 13 the tearing stress iscarried by the central portion of the front wall of the cover betweenthe tabs 13 and 14, but, as previously stated, once the tear is started,the stress is very slight. Furthermore, where it is desired to use anedge re inforcing member, the constructing of the tabs in this mannerpermits the use of an edge reinforcing member which grips the tab andthe front wall securely holding them together, and obviates thenecessity for use of other fastening means to hold the corner connectionin place.

I claim:

1. A container for roll paper, comprising a. cardboard box of a size toreceive a roll of paper therein, a cover carried by the rear wall ofsaid box, said cover having a downwardly folded front wall adapted tooverlie the upper edge of a front wall of said box, downwardly bent sideportions upon said cover, adapted to overlie the upper portions of theends of said box, said side portions having forwardly projecting tabsfolded inwardly to overlap said front cover fold, and a channeled stripover the lower edge of said front cover fold and said side tabs, saidchannel being pressed into gripping engagement with said front fold andsaid tabs to form a combined securing means and to provide a tearingedge for paper withdrawn from between said cover and said box.

2. A container for roll paper, comprising a cardboard box of a size toreceive a roll of paper therein, a cover carried by the rear wall ofsaid box, said cover having a downwardly folded front wall adapted tooverlie the upper edge of a front wall of said box, downwardly bent sideportions upon said cover, adapted to overlie the upper portions of theends of said box, said side portions having forwardly projecting tabsfolded inwardly to overlap said front cover fold, and a comparativelyrigid strip along the lower edge of said front cover fold and said sidetabs, said strip being secured to said front fold and said tabs to forma combined securing means and to provide a tearing edge for paperwithdrawn from between said cover and said box.
